Lonaconing Silk Mill

"The Lonaconing Silk Mill, also referred to as the Klotz Throwing Company, is the last intact silk mill in the United States. It is located in Lonaconing, Maryland within the National Lonaconing Historic District, and the site was nominated by the George's Creek Watershed Association for the National Trust for Historic Preservation’s list of America’s 11 Most Endangered Historic Places.
Open in 1905 and was fully operating till 1957.
The employees went on strike, and with that, the mill was closed by the company. The last payroll to 67 employees was made on June 23, 1957. Just seven days later, only six workers remained on the payroll. And by July 7, only five. On July 7, 1957, after a prolonged labor dispute over pay, the silk mill closed.

The mill is described as "the only remaining silk mill in the United States with its machinery, company records and workers' personal effects remaining unchanged from the time that the factory ceased operations in 1957."
